The present application', as to.A certain of" the broad subject-matter, is a co'ntinnatioi'rv of my application 'Serial Number 375,715,

-lled May 25th, 1907. Y

ln the accompanying drawings, which form a part of this specification, `Figure l is a section through a wheel telly, rim and tire illustrating one embodiment of my. v`inven' tion, the section being taken online l-g-l of .Fig Q: Fig. 2 is aside elevation of a-po'r-,

tion oi the wheel folly, rim and tire shown in Fig. 1; Fig. 3 is a section similar ltoj Fig. 1, showing a modified form of my invention.

Referring to the drawings in detail, the immoral 1 designates .the Wheel telly, ltoy whichis permanently secured 'the band or fixed 4rim inenibei2, which is provided at one side with a flange 3 having an inclined upper face el, and atv the other side With al downwardly inclined or tapered face The detachable rim member or rim proper G in the embodiment of the invention shown in Figs. 1 and 2, is split at 7, the Wedgepiece S which is cut from it being used to lock its ends in position. lt is provided with flanges 9 which serve to retain the endless tire retaining flanges 10, againstwhich seat the beads or' 'the tire 11. The rim 6 is provided with a number of inwardly inclined surfaces 12 and 13, one otwhich engages with the inclined face 4 on the band 2, while the other is engaged by the upper inclined tace o'l2 the'wedge portion 14 projecting from the keeper' 15. The keeper 15 is provided at4 16 with a. perforation through which pro'- jects the threaded end of av bolt 17 carried by the telly. The nut 18A screwed on this bolt' retains the keeper 'in position and causes it to directly promote the Wedging en- 1910. seriai'nasesee..

4gagement between the .lined and removable Patented iifpr. ll,

rinis. 'lhe opening 1G vin the keeper is made.

preferably of somewhat greater diameter than 'the bolt in order to permit the v4.vedge 14 to ride up upon the inclined face 5 of the fixed rim portion and seat itself evenlybetween the 'fixed and removable rims. The

keepers are 'preferably provided at* "their lower ends with projections 19 which act in the. .nature of fulcrnms, these .projections bearing against the ring 'of metal 2Q which is preferably secured-to the side olf the. telly..

nydesired nilmber of the' keepers may be vused .and tlieyinay be made in 'sections' 'oisuch length as may be found necessary. j By forming the keepers with ivedfhge-shaped por-v tions having both upper and lower surfaces inclined engaging with similarly inclined surfaces on.. the removable and. fixed rims, w

respectively, a more uniform seating of 'the wedges is obtained vthan il? the wedges were formed with a lower face whose elements were parallel with the axis of the wheel.

Find this a point of great importance as the weights to be ,sustained by the rim are oli such magnitude and the stresses to be encountered so violent that unless a very even seating of all the parts is obtained, resulting in the engagement of surfaces of considerable area, a disastrous grinding and Wearing'action is inevitable.

ln Fig. 3 l have shown a. modified embodiment of my invention in which my improved devices for securing a removable rim upon a. fixed rim are shown as applied to a removablerim of a different type than that shown in Fig. `1. The removable rim of .this ligure is shown as a welllrnown form ol' what is commonly referred to in the trade as a quicli-detachabley rim, that is, one. in which oneI of the tire flanges is made pemex able. The rim shown comprises an endless bandor tireseating portion 30 having an upturned ange 3l at one` side thereof against .which seats an endless tire retaining iange 32. The other side of the tire seating portion is bent downwardly and up wardly to form a channel. 33 in which seats a split locking ring 84, which serves to retain a second endless tire retaining flange 35. The band 30 has secured to' it a` member 36' .isY

provided with inclined faces 37 and 38, the

keeper 15 shown in Fig. 1 is provided with a Wedge portion which has upper and lower irelined faces engaging, respectively,-

With the face 38 of the member 36 and thel face 5 of the band 2. The construction and operation of the'keeper are similar 1n all respects to those of the keeper-15, except ence by the channeled portion 33.

Having thus described certain preferred embodiments of my invention, but Without limiting myself to. the details thereof as specifically shown and described, I claim:

1. A locking member for' securing detachable rims -to wheels, comprising a body por tion and a Wedge-shaped portion projecting therefrom, thewedging surfaces of the latter being oppositelyinclined to the plane of the body portion, the body portion Ibeing perforated and carrying a fulcruming pio jection, the wedgeZ portion andfulcruming projection projecting from-the same face of the body portion, butbeing located upon opposite sides ofv thev perforation.

Q. A locking member for securing detach- `able rims to Wheels, comprising a perforated body portion havingv projecting from one face thereof and upon ,opposite sides ofthe perforation-a wedge portion and a fulcruming projection.

3. In a Vehicle wheel, in combination, a. fixed Wheel member having-seats at each side thereof, at least one of said seats being beveled, a detachable tirecarrying rim seated on said member having a seat engaging the seat at one side of said fixed Wheel member, and haring av beveled seat facing the beveled seat on the fixed wheel member, but oppositely inclined thereto, and a keeper directly promoting the wedging engagement between said Wheel member and rim, said keeper comprising a body portion and a wedge-shaped portion projecting therefrom, the wedging surfaces of the latter being oppositely inclined to the plane of the body portion, the body portion being perforated and carrying a .fulcruming projection, the Wedge portionand fulcr'mmg projection projecting from the same face of the bod)v portion, but being located upon opposite sides of the perforation, and a straight bolt for securing said keeper to said Hxed wheel member, said bolt passing transversely through said fixed wheel member in a line substantially parallel lwith the axis of the.

wheehthe end of said bolt passing freely through the perforation in the body of the keeper, and a nut screwing on the outer end of said bolt and engaging the outer surface of said keeper.
